Perhaps you should try some spelling variations:
"risk estimation algorithms" » "risk estimation algorithm", "risk optimization algorithms", "risk optimisation algorithm", "pose estimation algorithms"
"_ optimized algorithms" » "_ optimizer algorithms", "_ optimization algorithms", "_ optimizer algorithmss"
"most optimized algorithm" » "most optimizer algorithms", "mot optimized algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"most optimized algorithm\") OR (\"_ optimized algorithms\"))) OR (\"risk estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( most optimized algorithm ) OR ( _ optimized algorithms ))) OR ( risk estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("most optimized algorithm") OR ("_ optimized algorithms"))) OR ("risk estimation algorithms"))*.
